2012，The author came to northern Shaanxi from Guanzhong，Transferred from weapons manufacturing industry to coal industry，That’s when I officially started my career in coal mining。Looking back，After ten years，I deeply feel the steps taken by Hanjiawan Coal Company，One step a year，Steadyly approaching M88 gamethe goal of creating a new sample of high-end first-class intelligent mines of the same scale with all coal。

May 2012，The first EML340A low-profile continuous coal miner of Hanjiawan Coal Company was put into use，Announcement that excavation has entered a new stage。The excavation system adopts "continuous shearer + four-arm anchor drilling rig + trackless rubber tire vehicle"，Compared with traditional cantilever tunnel boring machines, it has better tunnel formation、Fast tunneling speed、Advantages such as large-section excavation，Single entry up to 600 meters/month，Compared with the traditional cantilever tunnel boring machine, the single advance level is increased by 200 meters/month。

Only reformers advance，Only the new ones are strong。May 2022，With the joint trial operation of the company’s first set of intelligent rapid excavation equipment, it was a complete success，Excavation has entered a new era。This set of equipment is composed of an integrated anchor digging machine、Anchor transfer machine、Belt transfer machine for coal mines、Belt conveyor is composed of self-moving tail, etc.，With one-time lane formation、Safe and efficient、Three major advantages of process simplification，Especially suitable for excavation of semi-coal and rock tunnels under geological conditions in northern Shaanxi area，With both excavation, support and transportation synchronization、Foam dust removal、Autonomous feed、Digital truncation、Intelligent guidance equipment function。

Compared with traditional excavation equipment，This set of equipment greatly improves the excavation efficiency。Crusher mounted on the anchor loader，Can crush flat gangue and coal blocks with a thickness of more than 10mm，Completely solve the system jamming problem；The stepping self-moving tail can realize mobile curved transportation，To speed up excavation、Reduce employee labor intensity，Improve the safety factor at the work site，Played an important role in comprehensively improving the level of mine intelligence。

“Application of intelligent quick excavation，A good solution to the problem of "quick mining and slow mining"，Extraction imbalance’ is a long-term dilemma faced by the coal industry，The excavation speed and molding quality have also made a qualitative leap。” said Mr. Kou, the company’s deputy chief engineer who has been engaged in the coal industry for more than 30 years。It is reported，Now the footage of a single shift in Half Coal and Rock Lane exceeds 20 meters，As the operator becomes more skilled，There will be new breakthroughs。

Coal mining - the intelligent heart is stronger

When mentioning the coal mining face，Many people naturally have the image of miners with faces covered in coal dust。But you may not think of it，Today’s coal miners not only don’t need to work hard、Sweating profusely，And you can produce coal just by sitting in the centralized control room wearing clean clothes。

Come to the company’s dispatch center，I saw the central controller just click with the mouse，The monitoring screen immediately switches to the 214201 intelligent comprehensive mining working surface，With the roar of coal shearers，Reprinter、Scraper and other fully mechanized mining equipment are started in sequence，The waterfall-like "Wujin" follows the belt and runs towards the ground，Form a beautiful landscape。

This working face combines intelligent coal mining technology and "110 construction method" mining technology into one，The country’s first intelligent “110 construction method” fully mechanized mining working face for medium-thick coal seams was built，Achieve one-click startup of a complete set of equipment、The hydraulic support automatically slides with the machine pull frame、The coal shearer automatically remembers coal cutting and other functions，And equipped with intelligent video surveillance、Three-machine fault diagnosis and other supporting systems，The memory cutting rate of the coal shearer and the automatic tracking rate of the hydraulic support can reach more than 80%。

M88 gamePreviously moved and adjusted the working surface hydraulic support，Scaffolders must stand under this rack to operate，The operation is complicated、Requires manual reset，There is gangue leakage from the roof，There are risks to the safety of scaffolding workers。A shift support worker must constantly go back and forth to the work surface for inspection、Rehydration。Now using bracket electro-hydraulic control，Only one electro-hydraulic controller can adjust the number of racks that need to be moved。In the past, there were thirteen or four people in a class，Now 6 people can organize production，The goal of "safety if no one is around"，The goal of "safety if no one is around"。

System - the body of wisdom is thicker

The company pays close attention to and carefully studies the construction of intelligent mines，Consider intelligent construction as an important measure to promote high-quality development of enterprises，Achieve safe and efficient mining in mines。

“I went to inspect the belt conveyor in the main alley and walked back and forth，It will take at least more than 40 minutes。Now there is an alley patrol robot，We are sitting at the computer，It only takes ten minutes to complete an inspection，Inspection robot can automatically identify faults，It really saves time and effort。”

“In the past, the mine’s outer inspection line encountered rain and snow，We always rely on people to walk on the muddy mountain road，You will slip if you are not careful。Now there are drones，You can easily inspect the line just by operating the remote control。”

“In the past, underground vehicles were speeding、Difficult to supervise violations。Now using the intelligent auxiliary transportation management system，Not only achieves precise positioning of vehicles、Automatic collection of running status information、Intelligent security warning、Intelligent dispatch communication and other functions，It can also target vehicles running red lights、Capture and record speeding and other violations，Ensuring M88 gameefficient, safe and reliable transportation lines。”

"When accessing miner's lamp in the past，You need to use the light cabinet key to unlock，You may have to queue during rush hours，Sometimes I forget to bring my keys，Need to contact the administrator，Very inconvenient。Now there is an intelligent multi-modal recognition miner’s lamp charging cabinet，Not only brings convenience to everyone，Also saves commuting time。”

……

By promoting "mechanized substitution、Automation reduces people、Intelligent unmanned” working mode，Remove miners from heavy underground labor、Freed from the harsh working environment，Received unanimous praise from employees。

A new era of meritorious service、Strive for a new journey。The company will adhere to the work philosophy of winning with "wisdom"，Continuously improve the level of mine intelligence，With firm determination and belief in victory，With more passion and energy，Strive to climb the "intellectual" heights of the coal industry。(High Earthquake)
